I wonder if you might be interested in a potential collaboration regarding some clinical data that I have on chemokines and lower back pain. I did a protein panel screen (42 chemokines and cytokines) on the CSF from 7 patients with lower back pain. We have 2 CSF samples from each patient (60-90 days separate the samples) with some relatively good consistency across time. Perhaps we could combine these data with some pre-clinical data for an interesting paper.
